SEWING-MACHINE NEEDLE.

Application filed-January 24,1919. Seria1.No.-272,8 13.

tain new and useful Improvements in Sewing-Maehine Needles, of which thefollow ing is a specification.

Thisinvention relates to-improvements in sewing machine needles and theobject is to.

provide a needle into which the thread may be inserted with ease.

The invention consists informing a'hollow needle from a strip of metal,bent to substantially tubular form, and having a longitudinal slot'inthe sewing end thereof,

with a thread engaging ear at one end or the slot and an eye at theopposite or lower end and in close proximity to the point of the needle.

e, The invention represents a step forward in the art as disclosed inUnited States Letters Patent No. 1,07 3,140, issued to me under date ofSeptember 16th, 1918.

As compared with the device disclosed in said patent, mypresentinvention is more snnple 1n construction and 1t espec1ally prture, namely, the tendency 1J0 shear off the thread wh le in operation.

The inventlon isv more fully describedin the following specificationandclearly illustrated n the accompanymg drawing, in

which 1 Figure 1 represents the blank stripof metal from which theneedle is to be formed.

Fig. 9. represents the needle, formed by turznn g sald sheet intotubular form.

Fig. 3 represents a side View ot'a portion of the needle, at thejuncture of the larger and smaller diameters, and showing the threadengaging ear at 'oneside. t

elevational viewof the por f tion shown in Fig. 4, with the threadrestdesignates a blank or strip of metal, the upper portion of which isconfatented Mar. 9,1920.

I point l and immediately above the point where this point formationbegins, I cut a substantially semi-circular indentation 5 in thelongitudinal edge, at the side opposite that in which the slot 3 is cut.

This blank forms theentire body from which the finished needle is made.

The blank is turned into substantially tubular form, as shown in Fig. 2,the upper portion forming a body of larger diameter than the lowerportion.

The ear 2, by which the thread is engaged while inserting 1t-1nto theneedle, is bent,

- I In the upper portion, the meeting longitudinal edges abut, as shownat 6, while the lower portion ot the needle, that 1s,.the

as shown in Fig. 3,'to'torma spring or snap J device to prevent thethread from disengaging itself after 1t has been inserted The eye 5, 1nthe lower extremity of the needle, is partiallyclosed by the 0verlappingedge 7, and the meeting edges at the lower extremity are rolled into apoint 10; rides for overcoming one objectionable fea In inserting thethread, it is drawnunder the ear 2 and then pulled down along the needlebody, passing through the slot 9 and into the hollow interior of theneedle, until the eye 5 .is reached, where it passes out.

During the act of sewing, while the needle moves vertically through thecloth, the thread beyond the eye is, carried along with the needle, andto insure against the thread I being sheared off by the cloth, I providethis longitudinal slot 9., into which the thread 11 forced, and where itlies, protected from contact with the cloth, as clearly shown in -Figs4and 5'.

The construction of the needle is trelnely si1nple,;f and this tendencyto shear as the thread is entirely overcome.

. Having thus described my invention, I

1. A hollow sewing machine needle, whose.

cross section is substantially circular, one end of which 1s reduced indiameterand formed with a longitudinal slot terminating in an eye, oneedge of" the metal along the slot being spaced from the other andoverlapping it, to form a longitudinal opening or slot, and athreadengaging ear at the other end.

2. A hollow sewing machine needle pro slotted from the'top tothe eyethereby proslot.
